Good news, if you think of it that way. Most Mighty Mite guitar parts are from the Cort factory in Korea where they made your 270. They sell the Lo-TRS. But, understand that it may not fit because it goes deeper into the guitar's body. They also sell a regular trem. Their standard Floyd Rose copy. It is basically the same baseplate as your single lock. Just the saddles and lock bolts are different. It should drop right in, and then you'd have a locking trem equal in quality to the Lo-TRS. Some guys don't like any of the Korean trems, and so far they'd be right, because they don't wear very well. But the regular trem is still far superior a design than your single lock. The original Floyds have a rounded baseplate instead of the angles found on the Koreans. So they aren't a nice replacement. You could also just order 6 saddles, blocks, and bolts (sold together) and convert your trem over. Make sure you get the different heights for each string set.
